Thanks, 'preciated :-) Kinda can't help it thanks to the "wisdom" of
the Canonical Partners.

I wish I knew more about the topology of Linux sound software
archetecture. Maybe O'Reilly has a book ....

Yes, .wav files are more reliably played than .mp3 files. The issue is
that I have to deal with .mp3 files as a routine matter on a regular
basis, and converting them to .wav files is not only a PITA, but
obscures the fact that mp3 compression is inherently lossy, and then
reconverting them int .mp3 files doesn't restore the lost quality. I
didn't used to have to jump through hoops to play mp3 files. I don't
want to start doing it now, if it can be avoided.

It sounds like Nama is something I need to look into :-) Thanks. I'll
do it.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security 
threats, fraudulent activity, and more. Splunk takes this data and makes 
sense of it. IT sense. And common sense.
